Activeforever Acoustic Magic Voice Tracker II Array Microphone - Manual

Voice Tracker™ Array Microphones
for Lecture Capture
The Voice Tracker™ creates an exceptional signal to noise ratio by increasing its signal pickup
while reducing room noise. It accomplishes room noise reduction through a two-stage process.
First, it minimizes unwanted sound and reverberation by beamforming. Its digital signal processor
creates a “listening beam” (like a searchlight) that automatically and electronically focuses on the
algorithms diminish the remaining background noise and reverberations. The Voice Tracker™
increases its sensitivity by constructively adding the output from its six or eight “always on”
microphone elements. As a result, the Voice Tracker™ I has range of more than 30 feet for lecture
capture and the Voice Tracker™ II has a range or more than 20 feet.
Full Duplex operation for Distance Learning
The Voice Tracker™ II has a high performance acoustic echo canceller built in. This AEC, combined with a mute button and the
Voice Tracker™ II’s long-range, make it ideal for conferencing /distance learning applications.
Easy to use
Our patented beam steering technology, noise reduction algorithms, and AEC, all operate from an internal DSP. No software
needs to be loaded on your PC, and there is no drain on your computer’s processing capability. There are no moving parts, so the
Voice Trackers are rugged and reliable.
The Voice Tracker™ is an ideal microphone for lecture recording because of its ability to pick
Thus, you can pick-up questions from the class as well as the lecturer as he moves about the
room. Because this can be accomplished with a single, inexpensive microphone, it is an extremely
user friendly and economic solution. More than 300 universities use the Voice Tracker™ for lecture
recording.
